DOB vs. HPD vs. ECB: Understanding NYC Building Agency Violations

New York City has one of the most complex regulatory environments for building owners in the country. Multiple agencies can cite your building for violations, each with different triggers, penalty structures, and resolution processes. Keeping them straight is half the battle.

This guide breaks down the agencies that matter most to residential landlords and what their violations actually mean.

Department of Buildings (DOB)

The DOB oversees construction, structural safety, and building code compliance. If it involves the physical structure of a building, permits, or construction work, it is probably DOB jurisdiction.

Common DOB violations include:

• Work without a permit (this is the most common one by far)
• Failure to maintain the building facade (Local Law 11/FISP)
• Expired or missing certificate of occupancy
• Illegal conversions (turning a basement into an apartment without approval)
• Failure to perform required elevator, boiler, or gas piping inspections
• Construction site safety violations

How DOB violations work: DOB violations are categorized by severity. Class 1 violations are the most serious (immediately hazardous conditions). The DOB can issue violation orders directly, and penalties are assessed through ECB/OATH hearings.

Some DOB violations are self-certifying. Your architect or engineer can file paperwork attesting that the condition has been corrected. Others require a DOB inspector to verify the correction.

What makes DOB different: DOB violations often involve professional filings. You may need a licensed architect, professional engineer, or registered contractor to resolve them. This makes DOB violations more expensive to address than HPD violations, which are usually just about fixing a physical condition.

The DOB also tracks violations at the BIN (Building Identification Number) level, so they follow the building, not the owner. If you buy a building with open DOB violations, you inherit them.

Housing Preservation and Development (HPD)

HPD is the tenant-facing agency. Their primary concern is residential habitability. If a tenant has a complaint about living conditions, HPD is the agency that responds.

How HPD violations get generated:

• Tenant calls 311 and files a complaint
• HPD logs the complaint and may schedule an inspection
• Inspector visits the building (they are legally entitled to access)
• If the inspector confirms the complaint, a violation is issued
• The violation has a correction deadline based on its class

HPD violation classes:

Class A (Non-Hazardous): Conditions that are not dangerous but need to be addressed. Examples: missing apartment numbers on doors, chipped paint in a non-lead area, minor plumbing issues. Correction deadline: 90 days.

Class B (Hazardous): Conditions that could be dangerous if not corrected. Examples: broken windows, inadequate lighting in hallways, leaking pipes, defective smoke detectors. Correction deadline: 30 days.

Class C (Immediately Hazardous): Conditions that pose an immediate threat to health or safety. Examples: no heat or hot water (during heating season: October 1 through May 31), no electricity, lead paint hazards, serious structural defects, rodent infestations. Correction deadline: 24 hours.

What happens if you do not correct an HPD violation: HPD can re-inspect after the correction deadline. If the condition persists, they can issue additional violations with additional penalties. For Class C violations, HPD can arrange for emergency repairs and bill the landlord. They can also place a lien on the property for unpaid charges.

In rent-stabilized buildings, tenants can use open HPD violations to support a rent reduction order from the DHCR (Division of Housing and Community Renewal). This is one of the strongest incentives for landlords to address HPD violations quickly.

Certifying HPD corrections: For many HPD violations, you can self-certify the correction through HPD Online. You log in, confirm the work was done, and provide the date of correction. HPD may re-inspect to verify, or the violation may auto-close after a set period. For lead paint violations, you will need to provide documentation of the remediation work.

Environmental Control Board (ECB) / OATH

ECB is the enforcement arm. When DOB, FDNY, the Department of Sanitation, or other agencies issue summonses, the hearings happen at ECB, which is now part of OATH (Office of Administrative Trials and Hearings).

ECB is about money. While DOB and HPD deal with the physical conditions, ECB deals with the penalties. When you receive an ECB hearing notice, it means an agency has issued a summons and you need to appear (in person or online) to respond.

How ECB hearings work:

• You receive a summons with a hearing date
• You can appear to contest the summons, present evidence of correction, or request a reduced penalty
• A hearing officer reviews the evidence and issues a decision
• If you do not appear, a default judgment is entered for the full penalty amount

Default judgments are the expensive part. If you miss your hearing date, the full penalty is assessed automatically. Vacating a default judgment requires filing a motion with OATH and showing good cause for your absence. This is not easy, and there are strict time limits.

ECB penalties vary widely:

• A simple DOB violation for work without a permit might carry a $10,000-$25,000 penalty
• FDNY violations for blocked exits or missing fire safety equipment can be several thousand dollars
• Sanitation violations for improper waste storage are typically a few hundred dollars
• Repeat violations of the same type often carry escalating penalties

Paying ECB penalties: You can pay online through the DOB or OATH websites. Unpaid ECB penalties accrue interest and can result in liens on your property. The city can also intercept your tax refund to collect unpaid ECB debt.

FDNY (Fire Department)

FDNY conducts fire safety inspections and enforces fire code. For residential buildings, this primarily involves:

• Fire escape maintenance and accessibility
• Sprinkler system compliance
• Fire alarm and smoke detector requirements
• Exit signage and emergency lighting
• Storage of flammable materials
• Fire safety plans for larger buildings

FDNY violations are issued directly by fire inspectors and penalized through ECB hearings. For larger buildings (typically 7+ stories or those with commercial spaces), FDNY may conduct periodic inspections. For smaller residential buildings, FDNY typically inspects in response to complaints or after a fire incident.

How the agencies interact

Understanding the overlap between agencies helps you anticipate problems:

Tenant calls 311 about no heat:

• HPD opens a complaint and may inspect (resulting in a Class C violation)
• If the boiler is the issue, DOB may also get involved if inspections are overdue
• Penalties go through ECB

Building facade is deteriorating:

• DOB issues a violation for failing to file the FISP (facade inspection) report
• If debris falls, DOB can issue an unsafe building notice
• If the condition affects habitability, HPD can also cite violations
• All penalties assessed through ECB

Illegal construction work discovered:

• DOB issues a violation for work without a permit
• DOB may issue a stop-work order
• ECB hearing scheduled for penalties
• If the illegal work affects fire safety, FDNY may also get involved

Practical takeaways

• Check all agencies, not just one. A building can have open violations from DOB, HPD, ECB, and FDNY simultaneously. Checking only one agency gives you an incomplete picture.

• Prioritize by deadline. HPD Class C violations have 24-hour correction deadlines. ECB hearing dates are non-negotiable. DOB violation orders have specific compliance dates. Triage based on urgency.

• Show up to ECB hearings. This is worth repeating. The difference between appearing and not appearing can be thousands of dollars. Even if you are clearly in violation, an appearance with evidence of correction typically results in a significantly reduced penalty.

• Keep records of everything. Dated photos of repairs, contractor receipts, tenant communications, and inspection reports are your evidence at hearings and your protection against future disputes.

• Monitor proactively. All of this information is publicly available through NYC Open Data. Whether you check manually or use a tool to monitor your buildings, regular checks mean fewer surprises.

NYC's regulatory system is not going to get simpler. But landlords who understand how the agencies work and stay on top of their buildings spend less time and money on violations than those who react only when a notice arrives in the mail.
